GM2 gangliosidosis is lysosomal storage disorder caused by deficiency of the heterodimeric enzyme β-hexosaminidase A. Tay-Sachs disease is caused by variants in encoding the α-subunit and Sandhoff disease is caused by variants in encoding the β-subunit. Due to shared clinical and biochemical findings, the two have been considered indistinguishable.

BCL11B is a Cys2-His2 zinc-finger (C2H2-ZnF) domain-containing, DNA-binding, transcription factor with established roles in the development of various organs and tissues, primarily the immune and nervous systems. BCL11B germline variants have been associated with a variety of developmental syndromes. However, genotype-phenotype correlations along with pathophysiologic mechanisms of selected variants mostly remain elusive.

As the management of Pompe disease depends on whether an individual has infantile onset Pompe disease (IOPD) or late onset Pompe disease (LOPD), the question of whether the phenotype can be predicted from specific pathogenic variants is becoming increasingly important. We reviewed published cases of Pompe disease in which IOPD versus LOPD and pathogenic GAA variants were assigned for specific individuals. We then compared variant types and locations versus phenotypes.

Primary immunodeficiency (PID) is one of the causes of secondary autoimmune hemolytic anemia (AIHA) and Evans' syndrome (ES). Serum immunoglobulins should be tested in patients with AIHA/ES, as common variable immunodeficiency is the most common PID of secondary AIHA/ES. However, it is not fully understood how immunodeficiency is assessed, in addition to serum immunoglobulins.

However, the mechanism(s) by which changes in LD composition and dynamics contribute to pathophysiology of these disorders remains unclear. Apolipoprotein E (ApoE) is a droplet associated protein with a common risk variant (E4) that confers the largest increase in genetic risk for late-onset AD.
